In a small bowl, whisk together the mayonnaise and lime juice. Refrigerate until ready to use.
In a separate small bowl, mix together the orange zest, sugar, and the chili powder.
Rub each piece of salmon with about a teaspoon of olive oil followed by the chili powder mixture and let it stand at room temperature for about 10 minutes or so.
Before grilling the salmon, place your tortillas in foil and bake for 8 minutes until they’re warmed through.
Place your salmon in a grill pan over high heat and let cook on each side for about 3 minutes per side, until they’re deliciously browned. With a pair of tongs or your spatula, gently break the salmon into smaller pieces.
To build tacos, spread a layer of mashed avocado on a tortilla and top it with the chipotle-rubbed salmon, apple cucumber salsa, a small handful of cabbage, and a drizzle of the lime mayonnaise.
